crypto: caam - treat SGT address pointer as u64
Even for i.MX, CAAM is able to use address pointers greater than
32 bits, the address pointer field being interpreted as a double word.
Enforce u64 address pointer in the sec4_sg_entry struct.
This patch fixes the SGT address pointer endianness issue for
32bit platforms where core endianness != caam endianness.
